ELECTRIFIER FOR TREATING AIR OR OTHER GAS.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed May 25,1906- Serial No. 318.6%:-

To all LUh/(H'It it may concern:

Be it known that I, JAMEs H. BRIDGE, a subject of the King of England,(but having declared my intention of becoming a citizen of the UnitedStates) residing at the city of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Electrifiers for Treating Air or other Gas, ofwhich the following is a specification.

My invention has relation to an electrifier for the treatment of air orother gas; and in such connection it relates more particularly toconductive means for preventing destruction of the electrifier by anexcessive electric ply of air or other gas to the electrifier when theconductive means have been rendered inoperative by an excessive electriccurrent.

The principal objects 'of my invention are, first, to preventdestruction of the electrifier for the air or other gas through arcing,shortcircuiting, or sparking by introducing into the conductive means ofthe electrifier a fuse or fusible substance, whereby through burning outof the same the current is cut off, and, second, to provide theapparatus with means whereby when the fuse is destroyed to closing ofthe inlet for air or other apart the same.

gas into the electrifier to thereby prevent passage of untreated air orother gas there- T he nature and sco e of my present invention will bemore ful y understood from the following description, taken inconnection with the accompanying drawings, forming part hereof, inwhich- Figure 1 is a view illustrating in longitudinal central sectionan electrifier consisting of tubular electrodes concentrically arrangedwith respect to each other and with a fuse connected with the positiveelectrode, in this case the inner tube, and the line-wire, all embodyingfeatures of my present invene tion. Fig. 2 is a similar viewillustrating a disk arranged adjacent to the air-inlet of the innerelectrode, in this case normally held by a fuse, and a spring forforcing the disk against said inner electrode to close the airinlet whenthe fuse is destroyed; and Figs. 3 and 4 are detail views illustratinin, respec tively, longitudinal section mo ified forms of the disk andmeans for supporting and actuating the same.

Referring to the drawings, a is a tubular shown in Fig. 1, the

' 6, conductors 7, and

electrode, which is surrounded by a similarlyshaped electrode b,preferably arranged concentric with respect to the electrode a. In theelectrode a are arranged at suitable distances apart openings at, whichare provided at the side contiguous to the electrode 1) with projectionsor elevations 0. formed either by first cutting the plate and thenbending the cut portions outward or by forming conical projections inthe plate and then splitting or cutting the apex of each cone andspreading In this manner a plurality of projections or elevations a. areformed integral with the plate a, surrounding each of the openings atherein, which openings, according to the manner of forming theelevations of, may be square or circular in outline, as shown in Figs. 1and 2. However, the openings 0. may be formed without projections orelevations (L as shown in Figs. 3 and 4. The electrode a is closed atone end by an insulating-plate a, forming a chamber 0, while the annularinsulation (1 separates the electrode a from the electrode 6 and formsin conjunction therewith a chamber (1. In the high-tension conductor 1,leading to the electrode c, is placed a fuse or fusible substance 2,while a conductor?) is connected with the electrode b, and bothconductors serve to connect the same with a source of electric energy(not shown) to conduct a current through the electrodes a and b.

Instead of connecting the fuse 2 of the conductor 1 directly with theelectrode a, as same may be connected with a disk 4', of conductingmaterial, which by means ofa conductor 5, conducting-spring a conductivering, bar, or other attachment 8, secured to the electrode a, isconnected with the same, as shown in Fig. 2, for a purpose to bepresently more fully explained. In this instance the disk 4 is held inproper positionwith respect to the inlet a of the inner electrode a by afuse 2 and aring, bar, or other attachment 8. However, the disk 4 may besupported only by the fuse 2, in which case the same isheld suspendedtherefrom and. in a osition above the inlet- 0 of the eectrode a, asshown 1n rent thus conveyed to the electrode a may 5 vert oxygen of theair into ozone, the same will enter the chamber in volume andwill travelthroughtheopenings a of the electrode a from one side to the other,being thus divided into streams, each of which is forced I to passsubstantially through the cores of the silent brush discharges, andafter passing through the cores the streams are reunited by deflectingtheir path of travel and again forced to pass through the electricdischarges I before leaving the chamber (1 through the outlet (1 Fromthe outlet 0. the air or other as so treated can be conducted to anypoint or utilization or storage. (Not shown.) If other gas than air isto be treated, the same 2o will be conducted through the chambers c andd and be treated in'thechamber d by the electric discharges in the samemanner as hereinbefore explained with respect to the treatment of air.In order to treat a large volume'of air or other gas at a time, a seriesof electrifiers formed by the electrodes a and b may be arranged side byside in a manner not shown. The fuse 2, directly engaging the electrodea, as shown in Fig. 1, prevents 0 by burning out the destruction of theelectrifier through short-circuiting, the formation of electric arcs, orprolonged sparking. In instances Where a series of electrifiers areemployed the current is cutoff only from the 3 5 electrifier in whichthe fuse 2 has been destroyed, while the other electrifier will remainoperative. By such an arrangement, however, air or other gas enteringthe inoperative electrifier will leave the same untreated. In

4 order to overcome this disadvantage, the

electrifier, as shown in Fig. 2, is employed, in Which the fuse 2 bybeing destroyed permits the spring 6 to force the disk 4' against theelectrode a, and thus tocut off further admission of air or other gasinto the electrifier through the inlet-opening c 'by holding the diskover the same. However, the disk 4 may be permitted to drop by gravityover the o emng 0 when the fuse 2 is destroyed,

for w ich purpose the electrifier is provided with a sup vort e, intowhich the same descends and y means of which the disk 4 is 'Fig. 3..

held in proper position with respect to the electrifier, as will bereadily understood from In this instance the disk 4 contacts directlywith the electrode a. On the other hand, the disk 4, placed within theelectrode a, as shown in Fig. 4, and by being held in an open orinoperative position by the fuse 2, will be closed by the spring 9 atthe inlet a when the fuse is destroyed.

I laving thusdescribed the nature and objects of my invention, what Iclaim as new, and desire .to secure by Letters Patent, is'

1. An electrifier, consisting of electrodes provided with an inlet andoutlet for air or other gas to be treated by passage there v through, aconductor for each 'of said electrodes, one of said conductors havingmeans and a fuse arranged therein, said means adapted when sait fuse isdestroyed by an excessive electric current passing therethrough torevent entrance of air or other gas into SSLI( electrodes.

2. An electrifier, consisting of tubular electrodes concentricallyarranged with respect to each other having an inlet and outlet, aconductor for each of said electrodes, a fuse and a disk forming part ofthe conductor for the positive one of said electrodes, said disk adaptedwhen said fuse is destroyed by an excessive electric. current passingtherethrough to close the inlet for air or gas leading to saidelectrodes.

3. An electrifier,con sisting of tubular solid and .tubular perforatedelectrodes arranged concentrically with respect to each other,insulating means adapted to close said electrodes at one end to form inconjunction therewith an inlet and an outlet for air or other gas, aconductor for each of said electrodes, a fuse and a disk forming part ofsaid conductor, for the ositive one of said 6130'. trodes, said disk a(apted when said fuse is destroyed by an excessive electric currentpassin therethrough to close the inlet leading to said electrodes.
